Heya fellows,
I would some advice as to which Amprobe model I should for for? The 15XP-B (http://www.tequipment.net/Amprobe15XP-B.html (http://www.tequipment.net/Amprobe15XP-B.html)) or the AM-250 (http://www.tequipment.net/AmprobeAM-250.asp (http://www.tequipment.net/AmprobeAM-250.asp))?
I will be using the DMM for some DIY audio projects, like poweramps, speakers, matching jfets & mosfets, etc. My budget is around US$50, which is why I chose the 15XP-B in the first place, but the AM-250 looks good too for a little more money.
If there are better DMMs, please recommend them as well. Thank you for pointing me in the right direction!

I have the AM-270 which is the 250s big brother. Absolutely amazing build quality for the price. I really like Amprobe's new stuff.
I think the 15XP is a Meterman design, which isn't bad, but I think you will be satisfied with the 250.

I had the predecessor, Meterman 15XP, but gave it away to a relative who needed the non contact voltage indicator for his work.
I liked it and didn't have any complaints. I also got it used on ebay for 99 cents (I was the only bidder).
I notice a lot of surplus used Meterman 34xr showing up on ebay with a starting bid of $9.99 + $15 shipping/handling. There is often only one bid so for about $25 you can get a true RMS multimeter. You might try to get 2 so you can measure current and voltage at the same time. This should give you an idea what to bid.

Unfortunately for me, the seller won't ship to Canada otherwise I would probably have one. The local electronics shop sells the Amprobe 34XR-A for $170 CDN. Obviously caveat emptor with any ebay purchase.
Dave also reviewed this meter way way back in episode 6.
4 out of 5 multimeters are used (including 3 Flukes). I have another used on the way.

Is that two continuity beepers?

Thk's for the reply guys. I think I might go for the AM-530 (http://www.testequipmentdepot.com/amprobe/multimeters/am-530.htm (http://www.testequipmentdepot.com/amprobe/multimeters/am-530.htm)).
The AM-530 cost about the same price as the AM-250 & the 15XP-B. However, it is a True-rms unit, while the AM-250 & 15XP-B are not. Not sure if I really need this feature...
The 15XP-B can only measure to up 2A DC current, while the AM series are rated up to 10A.
Btw, I was looking at the accuracy info & found that the AM-530 is listed something like: =/-(1.2% Rdg + 2 LSD), not the usual dgts. What is LSD?

Yes, I believe so. I don't have it anymore to verify.
Top one might be for non contact voltage buzzer.
