You already have the RTech???
Are you looking to replace it then.
I'm with Jim I wouldn't have either. But if you really insist I chose one it would for sure be the kemmpi. Yes it's not as portable but will be a superior quality unit.
Just saw a kemppi at a reasonable price what I'd get if I shifted the r-tech and wondered...
I'm sure the r-tech is fine for me if there was a massive difference I'd make the switch, if the r-tech dies ill take the opportunity to upgrade I'm sure.
I do indeed Ill stick with the r-tech for now just thought it consider a change since it is still unused. Getting tungstens rods and gas ordered on payday then can start playing
