i use several stylii.
best is one i got at verizon. (they will discount stuff. my gt was 174, 25 off. ). it cost about 12 with free fed ex!
it has a hollow rounded soft rubber tip.
another i got off evilbay, has a slanted harder rubber tip. does not work as well but cost 5 for five of them. works ok, just not as well.
have not seen an app that did not respond to stylus as if it were a finger.
