Very nice! I did something very similar last year. Back in the mid-90s, I fell in love with the idea of a Litespeed Ultimate. The last few years, I've looked for a frame in my size at a price I felt was fair, but it seemed like all the late-90s Ultimates were 57s, or 61s, but not 59, OR they were asking > $1500 for a 25 year old frame! FINALLY one came up on Ebay, a complete bike, but with all the components essentially worn out. The price was pretty good, and because it didn't present well nobody else grabbed it while I made up my mind.
I initially built it up with Dura Ace 7410 kit, to be the bike I wanted back then. That was really nice, and I loved that build, but I'm a little old and fat for 39x25 as my lowest gear! So I bit the bullet again, and built it up with R8000 Ultegra.
I confess I was a little afraid that I'd get the bike, and build it up, and find it to be nothing special. But the opposite is true! It turned out better than I'd hoped and now my other bikes are practically languishing, because I keep taking the Litespeed for every ride.
EDIT: It came with the original Time carbon fork with threaded alloy steerer, and since it's in good shape, I kept that.
