I have one that Phantom gave me last fall. It's a real comfy seat softness wise, but it pushes me too far forward. I'm 6'2" and it threw off the angle that my legs came into the forward controls. I could have adjusted the forwards, but I put the seat on the shelf for a while and haven't gotten it back out yet this spring.
It's a great seat for a shorter person. It's not bad if you're taller and don't mind sitting real far forward. It's real comfy in the behind (although I haven't tried it on an all day ride, but it would definately be better than the stock pillow that I've done a lot of long days on.
You might try picking up one of the Stock Solo seats off someones Low Model. These sit you an inch forward of most seats. I see them on eBay for 50 bucks from time to time. Sometimes less. Make sure its from a "Low" model.

I have a reach seat on my '04 Custom, only 900 miles (200 by me). It came with the bike when I purchased it, and am looking for a new one. I love the comfort for my rear, but it puts me closer to the controls than my knees would like (I'm 5'11"). The other thing I don't like about the seat is on fast takeoffs. The top of my arse slides off the back.
I'll probably be getting a new seat soon, and when I do, I will be selling the reach on ebay.
