DJD,
The 188 is a GREAT boat. Actually has more usable storage than the 198. Front deck is the same, area wise. No underseat storage due to that is where they put the gas tank on the 198. There is more storage in the bilge area on the 198 due to that fact. Storage in the front deck step on the 198, but not dry or much space. Love the coinbox on the 198,but that allows for only two seats but I can't say that will ever be an issue for me.
There are some good deals out there on some used 188's, but not many. Those that have them love them. I was looking at a VERY low hr 188 when I bought the 198. Major selling point on new, original owner warranty, and the 150 HP. At this point in ownership, I am pleased with the purchase. Would I purchase it again?? Probably....Maybe......but I would be just as content with a 188 for my needs/use. If you want to take a ride and look it over, get with me sometime.

Heading to Florida in two weeks. Hope to put some big girls in it. 
