I am also finally converting to kegs, and based on the research I've done thus far there seems to be very little difference in the stored product for the average homebrewers' storage times. As mentioned previously, most beers benefit from a little conditioning time. I plan on only bottling my belgians and any imperial stouts, etc. One thing I might recommend is going with 5 gal kegs instead of 2.5 gal kegs. You already brew 5 gal batches, and it cuts your cleaning in half.
