Bench PSU options am I missing anything?

Hello everyone, I am a beginner here and I want to see if I am missing anything. After many years of watching the eevblog and wanting to get into electronics I bit the bullet last year and started my journey. I am in the process of building a lab and need a power supply. I do not want to get one of the ultra-cheap ones on AliExpress or Ebay. My budget is around 200 usd I do not want to go much past that amount.

I am primarily going to be building guitar pedals and I am going to start working on designing my own pedal. The design is going to be based on a Fuzz Face circuit. The pedal will run off of 9v and likely use less than 10mA. This circuit, like other fuzz pedals, can sound and act very differently when the input voltage is lowered. I need a basic one output dc power supply. I assume a linear one would be better for the kinds of things I am doing. I want to have a good granularity on the voltage and current output. Guitar pedals typically run off of 9v 100mA power supplies. I do not plan on trying to design anything that will go past 18v and I deffinely do not need high amps.

I am interesed in something new and I do not want to get one used or try building my own at this time. I have been looking at alot of options online and I have found the UNI-T UDP1306C. This power supply looks to me as one of my best options given my budget. Are there any other power supplies that are out there that I should consider looking at or is this my best option?

The UNI-T UDP1306C appears to be a switching power supply. For your guitar pedal projects I'd use a linear supply.

The supplies made by Korad have gotten a lot of attention here, e.g. the KA3005 and KD3005 and you can find them for around $100.

Have a look at these. https://www.volteq.com  They're not fancy programmable supplies but they are reliable and easy to use . They have gone by many re-brands like Mastech, Hyelec, HeTest, TE, ect
All based on the HY3003, HY3005 and HY3010 so if there is a problem (rarely), they're easy to fix.

Advise stretching your budget a bit and get a 2- or 3-channel supply.  Lots of situations where multiple voltages are needed.  Many 2- or 3-channel supplies allow parallel or serial connections of 2 channels to get more voltage or current.  Most 3-channel supplies have only 2 that are continuously variable with the third being one or a few fixed voltages.  However, there are a few 3-channel supplies that have only one continuously variable output and 2 fixed. 

eBay can be a good source of good brand, good condition 3-channel supplies at cheaper prices.  I’ve gotten used PSUs on eBay that were just as good as new ones I’ve bought.

UDP1306C is a linear PSU according to the specs.
