Honestly if you can swing it i would do the mod yourself but if u have the cash buying it from swamps is not a bad route. i have got alot of things from them over the years and have always been happy with them
The Diy mod is well, cheap, and it does make a difference. I can't think of anyone that has done the mod then swapped in a swamps Idm to compare so can't tell you if there is a real performance difference between a Diy and swamps Idm.
