I found a nice 2010 North Evo, would that be good for me?
Yep will be fine... but its a few years old. make sure you pump it up hard and let it sit for awhile in case it leaks.
Check all the lines and attachments for wear.
Best if you've an experienced mate who can check it.
Remember if its cheap will probably be for a good reason. Breakages wont be fun....
