I'm looking for which mech mod will be my next, i currently have an ehpro Sentinel from Madvapes. I'm stuck between the Private V2 and Panzer on fasttech. I like the colors and the look of the Private, but i also like the simple colors and look of the panzer. The Private is $21 and the panzer is $32, they both are ss and brass (Private also has copper).Which mod would hit harder/ last longer/ Not be a pain in the ... with the contacts and such?
