I got the Ridgid 6" jointer recently and it is a joy to use. Like you the 8" was out of budget for me and space as well.
Just recently a member had one to sell on here, of course it came up right after I bought mine, but thats my luck. Check the classifieds here and see if he still has it, it was brand new I believe.
Anyway, the Ridgid gets a lot of good reviews and seems well made and actually a very quiet running machine. Mine was easy to set up and adjust, and is really a nice addition to my shop.
On the HF jointer I have only ever heard of one person who bought one, and he did not have a positive experience with it.
