Who has had a chance to weld a lot with both of these guns and how did you like them? Price and ease of getting parts and how well they welded?

I'm wanting to get a millermatic 252 and I have only welded very little with the 30A and well liked it but wasn't long enough to really get a good feel for it. I have welded with the PrinceXL push pull gun just not the Prince XL spoolgun. I know it was a very light gun but there isn't much pricing online and what I did find was pretty high. I personally wasn't happy with the princeXL push pull, it wasn't very reliable lots of hickups everyday trying to weld with it although i was using a 50 ft+whip but I do like that it is very light.
Miller 30A I don't think will be a problem getting parts and the price is very good on it but weighs more.

I tried the search but couldn't find much on the princeXL and not wanting to totally rule it out yet.

Please tell me how you feel about these two guns??
Thanks
Chris
