short liner recommendation

I tried some Novara short liners under my pants but the chamois plain hurt. Are there better ones out there or should I just buy some regular bike shorts to wear them under my pants?

I use the Andiamos all the time without problem or discomfort, and they’re cheaper than the Novaras. Sometimes they can get kinda bunchy on longer rides, though. Supposedly wearing regular bike shorts under pants will destroy the fabric.
