Welcome from NJ. Personally, I can never go wrong on Amazon.com for my gun accessories. They have a good assortment of SP101 rubber & wood grips from different manufacturers (Hogue, Pachmayr, etc). Their prices are good enough to try out a few different ones to see which you like best
Yeah, my Hogue grips for the SP101 22 lr, cost me $18.99, delivered, last year. There is a trick to using Amazon. Put the item in your cart...and wait. Over a few days, the price will go up, then down, then up a little, then down. Repeat...
Watch the trend, buy low! Sometimes, a product will become "unavailable" from a certain vendor. But they show more vendors that have the product at that time. Many times, the prices are lower than your "low" price, from the watching game. That is how I got my SP grips for $19.00, down from $22.00
