I routinely run thick agarose gels for PCRs. I *always* use 1% normal
agarose (I like BioRad's mol. biol. grade) + 1 - 4% NuSieve. This works
fine, and saves money.
Above 5% total, I use pure NuSuieve (it's just possible to do 6%, which
resolves fragments well below 100 bp).
Incidentally, we reuse the thicker gels - just melt 'em down, squirt in
a bit more EtBr, and pour. For straight analysis (*not* preparative) I've
used gels 5 or 6 times.
Hope this helps.
