guy over on modulardepot.com has been running a 125 shot with no problems me personally I would stay with a 75 to 80 shot , maybe 100 but not sure LOL...
I'm sure you can barely used kit for around $400-500.
You can get a bare bones kit for probably around $500-600.
Or you can get an nice safe kit with all the goodies for around $1000.
If it were me, I'd look around for kits that people barely used because they made the mistake of buying. If nothing, I'd buy a well equipped kit for $1000.
