I agree with you, a lift is nice, and it'll lift the S10 with no problem at all. I have the OEM debris guard on mine, and I don't feel confident of the load being placed on that single bolt at the rear of the guard that threads up into the engine when the bike is sitting on the lift. Might never be a problem, but if it was, it would end up being an expensive one.
If I got another lift it would be a table lift. I think they're better for maintenance than the undercarriage lift, though they definitely take up a lot more room.
