Let me echo the welcome and let me also echo to try used first. Older Bears are great shooters. Used but quality Grizzlys are out there for a fair price.
Take a look at the classifieds here. Ask lots of questions of the seller. Look at the seller's posting history here on TradGang. And get lots of pics of any bow you're about to buy. (tips, riser, belly, back, fades, etc)
I own an old Super Grizzly and a new Super Mag 48. The older bow is a better bow in my opinion. The Super Mag is OK, but the Grayling bow finish is better in my opinion.
Just an example: my daughter bought her boyfriend a 45# Bear Grizzly, Grayling edition, probably from the early 70s, for $100 off craig's list. It was in near new condition. Buy smart and enjoy your return to archery.
