We buy a lot of our hydraulic parts off of RG Group. For the most part, they have what we need, but if they don't have it they are able to get it to us within the next few days. Being in the oil field we need things sooner than later, but if they had everything that we needed when we needed it the store would have to much, much larger. Overall, I'd say they're a great company and I'd highly recommend them.
