Not too great; every day I come across pretty good words with the suffix '-able' on the end. Only the very rare one is barely good enough for me to get, most I put on my list (see sig). Still a lot of cool brandable words like Rippable.com, hurtable.com, hittable.com, houseable.com and Slammable.com available, you can reggem if you like; although they are cool, and many are using keywords that have viable use like yours, very few -ables have caught on and it's a real hard sell in the industry. Especially not going to get bids for them when there are still so many available at reg fee and the buyer can just be inventive and find their own.
You might check around and find the odd one sold, but it's a rare very good one. Best to stick to regging new ones for personal use... I got reggable.com for available - reggable - domain names, ha, and plan to develop.
Mashable.com made a nice service out of theirs.
To sum: you may sell it, but I think it's a skinny chance and I wouldn't recommend regging these unless you find an absolute gem, or one you really want to develop yourself.
Hope that helps
