theres some great deals popping up on craigslist right now.. i know your in merrit but check them out if you ever come down this way.. especially usedvictoria.com
if you find a pair and if you want, email me and if you could arrange for payment i could pick them up for you and hold them till your next trip over - vancouver or vancouver island im back and forth almost weekly.
As for telescoping or not, telescoping is nice becasue it gets your lines way out there and covers more space, but can be difficult to use on a smaller boat. Also, at 60" long x 10lbs theres alot of force put on your hull, so you need to make sure its well enough enforced.
I would go telescopic, and even if you dont use them extended you have the option of doing it, but for a 19' boat i wouldnt let that be the deal breaker.
