Well, after much research I finally purchased an Siglent SDS1102CML from Tequipment.net. So far I love the scope. Here are the things that swayed me from the Rigol 1102. (Larger display, larger memory depth, Physical knobs for both channels, quieter fan)
I also considered the Hantek's and although the higher res display was a large draw, I didn't want to deal with the funny timebase (2,4,8).
The only 2 annoyances I have found so far with the latest firmware is the fact that the probe compensation setting is reset to 1X when the Default setup key is pressed. Also the scope always asks to choose the language on boot.
I hope these 2 issues are addressed in the next firmware revision.

the 2 issues you said are not problems. they are designing issues.
1.default setup 1X is to restore the factory settings. Do you want it at 10X?
2.the language section on boot is for the customers to choose the language easier if you want to recover the version that do not have this section, please update the older .CFG file.
As Siglent local distributor and also professional with electronics and T&M equipments I will give my opinion what is based to long time experience.
1: I recommend 10X is default. (note 1) I can give many arguments for this if need.
This is normal recommended setting. Peoples need understand that use 1x probe ONLY if it is nessessary. Normally always use 10x probe. (also because
bandwidth but also for
safety)
There is many oscilloscopes what as factory default option is also sold with only 10x probes.
Also this is, as well as I know, very common working practice in every lab.
In classroom every school boy and girl need also learn this lab practice in first lesson in scholl electronics lab room. Turn always probe to 10x as default always before and after use if you have probe where is this selection. I hope also today young not experienced teachers teach this.
All know why there is so much 10x HP and 10x Tektronix second hand nice probes for sale around of eBay etc. This is because professionals "default probe" have been 10X tens of years. In long time ago normal package of example Tektronix analog scopes have 10X probes. (and never 1x 10x switchable probes)
2: It is good that in first power up boot customer get automatic menu for language selection. If example language is "accidentally" chinese and western user who have not yet enough experience with this equipment do not easy find how to set language what he know. It can do it example until boot up counter is 10.
Now it is very frustrating if use more this unit and every start it ask language. Why it ask it in every startup. After weeks, after months.. many times per day if frequently use scope.
I recommend that it works so that when people get it from package it ask language and perhaps example 5-10 first times (due to fact that some shop may start scopes some times for check equipment is not DOA fault. Then after count it shuts off this automatic language menu with normal boot up.
If user want he get this back with using some "deep recovery" option in menu what resets all to exactly factory state, all memories, all user data, even selfcal data.
Wink:
Then also this solution may be clever with many reasons: add something what is example in old well known Hewlett-Packard (Agilent) many equipments.
Boot up with one or two key pressed during power up boot. It recovers unit to deep factory default state.
It need do so that even if oscilloscope is crash down due to some fatal FW bug and it can not even boot after it (due to some corrupted stored data).
This power up with one or two key pressed drops it always to factory state resetting all, even selfcal data and every user memory and so on "and it drops to ground with his legs as cat".
After this, also language selection may pop up, all what have been exactly as received from factory exept power up boot counter.
(Note 1: If oscilloscope have automatic probe factor detect then if input BNC is without connected probe, then it need set defaul 1X. This scope do not have this feature.
