Apologies for not updating this post. I bought a little used Lincoln Weld-Pak 100 for I think it was $75 It has worked well on my mini build, I got a cart and tank with it. I know I would prefer to be running gas and solid wire because cleaning welding slag is a pain in the rear even though it was a very small build. I went through a little bit of a learning curve but part of my difficulty were the issues I've stated below. I did a couple things that I believe helped a lot and would probably benefit most used wire feed welders.
1. Replaced the cheap tin ground clamp with a thicker stronger clamp, cleaned all wire leads and connectors - I could see immediate improvement
2. replaced the feed roller
3. cleaned the trigger contacts and replaced the liner
I love this little welder and unless it breaks beyond repair I will probably keep it forever. It would be really nice to have something bigger that would single pass thick plate but I only have 110v anyways, plus I get more practice having to learn to double pass and make my welds really count. Still, the welding slag kinda sucks!
