tubulars with a small amount of stan's or orangeseal are extremely flat proof.
Tubular wheels are lighter.
Tubular tires from uk/eu suppliers ~ $65 if you wait for deals (veloflex arenberg/roubaix/vlanderen).
Tubular tape is easy, if you don't wish to glue.
If you are serious about lightweight wheels, the problem with tubulars is in your head.
High-end clinchers with latex tubes are super nice as well - and about the same price.
Edit: Vittoria g+ tubulars for $49, veloflex from $65.

i think it's funny, guys riding $5000+ bikes, disc brakes, carbon wheels complaining a small price difference for tubulars as a reason not to convert.
