Alpha Cat 18 How good of boat is it??

Hello all,
Trying to get some info on the Alpha Cat 18. Not new to cat sailing having had two Nacra 5.2's over the years but have been out for going on 10 years now. Started searching for a Nacra 5.2 up here in the Seattle area or perhaps a 5.8. Not much going on or available here at this time although I have found a Prindle 18-2 which I am have a tough time connecting with the owner for look over. I came across the Alpha Cat 18 that has been floating around this site and others for a while and John the owner has done a nice job of going thru it and bringing it back. I have not yet had a chance to look it over other than pictures and talking to him as the boat is in Boise at this moment. It looks to be rigged much like the Nacra 5.2 which I like but I can't find much else about them...so here I am looking to see if anyone knows how they sail. I prefer the Nacra style hull as you can bury the outside hull pretty deep without a pitchpole and the Alpha does not have that...I have not sailed a 10 ft beam cat before and it seems that you can power it pretty hard but when it is too much it may pitch pole easily but again I have no experience with that width boat. He is asking quite a bit for it, too much in comparison to the age of the boat but he has done a lot of work on it and the trailer plus he claims the sails are in great shape...would be unlikely but possible...any help would be great,
