For just regular trim/moldings, there's absolutely no reason for a sliding saw nor a 12" saw. You may find you want to use it for larger boards later, but I never have. I have a 10 Rigid, partly because of their warranty. However, when I tried to register the saw they "denied" me and said I had to physically cut out the UPC code and mail it to them. This was weeks later, and though I had cut the code out of the box and still had it, I had already provided them with everything they needed to honor the warranty ( everything they specified to send), including the actual receipt. I never did register it, and won't buy another Rigid tool because of it. But I don't have any complaints about the saw itself.
