    What are you trying to do? A decent plasma cutter is not a small investment, and will be a different machine than a welder, although the two look similar. With welders, even if you don't want to weld aluminum it's not too hard to put $1000 into a passable setup.

    Without knowing exactly the kind of stuff you want to do, it's kinda hard to make any recommendations. Plasma cutters are a dedicated and specific design that really doesn't share much with welders. Unless you want to get a combo device that's mediocre at both. After welding with oxy-acetylene and MIG for decades, I finally stepped up to TIG since I've been doing a lot more fabrication for racecars. I really like this Miller Dynasty 350 unit.

    Hard to go wrong with either Miller or Lincoln.

    Well if that's the case, since you clearly have a camera, show us some pictures of your welds on either sheet metal or really thick plate.

    A good test of a plasma cutter is to actually weld those cut ends back together.

    correct.

    also i'm going to step out on a limb and say anyone asking where to get a good "multipurpose welder with a plasma cutter" doesnt really have any business using either

    Can/Would you recommend one of those small, portable oxy/acetylene rigs?

    Sure, it depends upon your use. A good deal is the Northern Tool Torche kit for $200:
    .

    If you want to do brazing, you'll want to pick up an additional tip that spreads the flame out more.


    For emergencies and light-duty, I actually take one of these to the velodrome:
    Bernzomatic baby torche kit:


    I was actually able to repair a friend's bike between heats (had gotten caught up in wreck and snapped bottom of rear-dropout off).

    Where do you get the tanks, how much do they cost and how much to re-fill?

    what about this kit with tanks:
    http://www.harborfreight.com/portabl...nks-65818.html

    one more question, can you braze items as large is dropout/stays with the Bernzomatic OX2550KC Oxygen/Mapp Welding Torch kit? It'd like to be able to do braze-on canti studs and replace dropouts, maybe a disc brake tab on a stay and a small tube to brace the stay against braking force.

    Most of these machines would be overkill for cooking spam. That said, you may be correct.

    Welding-supply shops will charge about $50 to re-fill tanks. Some swap out pre-filled tanks for yours.

    Yes, the small torche kit can do all that. I've even built a recumbent from muffler-tubing using that little torche. Only issue is that the oxygen-tank only holds compressed O2, not liquid, so it lasts only about 15-20 minutes. At $8/apiece, it gets pricey if you have a lot of brazing to do. It will be fine for a single-bike project, but if you plan on doing more than what you've mentioned, then the bigger torche will cost less in the long-run.
