Millermatic175 M-10 gun conversion questions?

[Sapper]

I have had my millermatic175 now for about a year and I really do not like the "MIGmatic™ M-10 Gun". There is no real welding store within 3 hours from me and I would like to find a gun that is more like the Roughneck C-3012 Gun 12FT (but not $300). I don't like the nozzles on the M-10 gun and I would like to find a more industrial nozzle like the larger machines I am most a custom too. I am also curious if anyone knows of a tweco number for .035 contact tips (25 per bag) rather than the more expensive 10 packs from miller?

I had a Tweco style 180 amp made up for my 210 and only cost a little over 100.00 at the local welding supply.
