Good tubs should be OK. Don't bother with glue - use Tufo tape and take some sealant for tubulars with you (and use it also as a preventive measure).
Vittoria Pitstop which Hippy recommended to me when I went for the tubular tyres first time is good for all the on site repairs, but Tufo Extreme sealant is better as a protective when you treat your tubs beforehand..

If you're using tubs in the high mountains (and you should) then glue them. Tape isn't up to the job of high speed Alpine descents.

Don't by cheap tubs either, as EEI says, they are a false economy.
