updating welder

[studebaker]

I now have a Lincoln SP170T mig that has served me well and a friend wants to buy it. I am thinking about getting the next level of welder such as a Lincoln 215 or miller 210. Almost all my welding is on 22 thu 18 ga with somtimes thicker stuff. Any body got any feedback on these mig welders ?

I like blue ones...... altho that HTP 200 is looking somewhat tempting...
