wrist problems are frequently related more to improper fit to the bike, or riding style. many of us 'formerly bitchin' dudes' (a.k.a.: old farts) here grew up riding MTBs long before any suspension, and learned how to keep a firm grip at the bars but have loose arms to allow the bike to move under us, and that translates into a riding style that results in less wrist discomfort on any bike. sizing is one of those things people tend to overlook or forget to mention when talking about bikes (just like you did on your initial question); you just have to ask. frankly, if i were in your limited-$ shoes, i'd check to make sure the bike i had fit me. (a good shop should be willing to help you with a proper fit; and knowing how your bike should fit you is something you're going to need on every bike you ever own, so it's a good thing to figure out before you start buying stuff.) it might be that the bike you already have can be made to fit you better (longer stems are common for guys our size), and that may alleviate your discomfort for less than what you wanted to spend for now. depending on what year your Sorrento is, if everything else is good and you've already got your fit nailed, you might even consider looking for a shock that you can put on it. if your bike is too old, it might not have been designed to be 'suspension ready' geometry, but many are; you'll just have to check that to make sure you can get a suspension fork that will have roughly the same axle to crown race dimension as your stock fork. it wasn't me that mentioned the XL frame size, but they were probably right, as were the comments regarding the difficulty finding larger bikes for sale used. i have a high enough Ape Index that i flat-foot (with bent knees) a GS Adventure with longer-than-stock custom Öhlins, and can vouch that bicycles in the taller sizes like ours are fewer and farther between than bikes closer to the middle sizes. you might have much better luck finding a suspension fork that someone upgraded out of in a fit of 'upgrade-itis'.
