See what the LWS carries. Smith is certainly top shelf, but if the local store doesn't carry tips, you may have to wait for the Wells Fargo wagon to show up with your mail order replacements to finish a project. I can pretty much guarantee you that Victor tips will be locally available (knockoff are also available at my local Ace Hardware in a pinch, but knockoff torch parts ****). Harris probably too (because Craftsman torches are Harris).
Another quality brand not mentioned is ESAB. Again, you probably will not find parts for it locally.
