Not sure how much you're willing to spend, might be worth it to go talk to a dealer about financing. I went in to talk about a boat and ended up walking away with a brand new 17' montauk. The resale value on whalers is so high it's almost worth it to buy a new boat over getting one used. If you do buy one used, I recoment checking out www.boattraderonline.com.
Good luck, I love my boat in the near year that I've had it, can't go wrong w/a whaler.
Thanks for the comments ibn. I went down to the BW dealer in Fife a couple months ago and was tempted plenty by the new ones. I've looked high and low for many months. Probably looked at 30+ Whalers. Finally found one I couldn't pass up on Friday. 1984 15' Sport Center Console. Original owner, always garaged, and in outstanding condition. Matter of fact I may just have to go out in the garage right now just to sit in her for awhile and have a cold one! :beer1:
