I have the lincoln weld pack 100. For thin gauge sheetmetal it is nice, fixing exhaust, even welded up a strut, the bracket that the spring sits on, cause it rusted through causing the wheelwell to rub on the tire. Drove it around for a long time and it held, now the car is just sitting because there is too much wrong with it to bother fixing, but the strut was still holding. It is easy to carry the little welder to where you need it and 110 is convient. If you do mostly smaller projects and sheetmetal, I would go for the 110 mig. If you do a lot of thick plate like fred said, then go for the 225. I think my 100 welds up to 3/16" if I remember correctly. I built a cart for my 110 for about $10. Nice being able to roll it around most of the time and have it off the ground. They wanted $100 for a stupid cart for it where I bought it from.
the Lincoln mig is great for bodywork, and light structural, but for more serious work, get a Hobart Handler 140. They run great, come set up for gas, but can run flux core with no modifications, and use standard Miller parts available at any weld shop. I have an old Snap-on YZ-217, almost the same thing except it uses Lincoln parts, and it can burn a mean weld. You want a mig machine with at least four heat settings, IMO the little two setting machines are worthless. If you want a really good machine, though, save up your pennies (for a few years) and get a Millermatic 250. I think they only offer them for 220v, but most Millers now have Autolink, so you can plug them into almost any ac voltage without having to re-link the power supply. For stick, I use an old Miller Dynasty I picked up off ebay for way cheap, it does ac, dc, stick and tig. If you get a dc stick machine, don't buy rods at HD or Lowes, they are for ac only and make a crappy weld on dc, no penetration and splatter all over. They weld great on ac though.

Yeah, Lowes also sells welding carts in the price range.
I made a steel cart years ago but somehow it was hacked up and became part of various projects. I keep trying to save scraps and leftovers to make another one, but I keep recycling so oh well. So, my two welders and my plasma cutter sit on a moving dolley.
It's a shame because the cart was nice... had three shelves that slide out and retract (and lock) so I can change the wire spools without having to lift the units off, or out of the cart. Next to the three welder-sized shelves were a full-height framed out area where I put three bottles. CO2/Argon for wire welding, and Oxy/ACY for gas welding.
