Airdog 165 and 150 trade for 200 or 220

I have an original Airdog 150 (had been used) and a Airdog II 165 (never been hooked up). I would like the try an trade both of them for a 200 or a 220. They are not hurt at all I just need a bigger one. I need to keep the lines so it's just both pumps and bases

Might sell for right price
