If you want a beginner mech that doesn't have the bells and whistles but will still hit like a train and take a pounding look at the kamry k101. I have had one for a few months since I started rebuilding more seriously and it's worked perfectly every single hit.
The only trouble I've ever had is the locking button sticking when I screwed it down too tight, but I can't blame my kamry for that. Also, for under $30 at last check it's worth a shot. Basically all mechs do the same thing, the two main important things are a good *safe* battery ( remember electric cars catching fire? same batteries, think about that in your hand) and a stable *safe* coil.
If you want the name, a nemy clone is a good start as is a magneto. Just consider where you will use it and add in 10%-20% of abuse for wear and tear, drops and etc. Just fyi, even my $150 SVD vv mod has survived drops from over 5ft and gotten only cosmetic damage.
