Just my opinion, but in my experience, some of the best stuff is highly visual, and not to long. How about:
'Recapped' routine using bic pen - greg wilson.
Money routines e.g. Hundy 500 / Extreme burn etc - changing paper to money or a bill switch (there's a new Noblezada money DVD which has a lot of not to hard to perform visual stuff)
Sponge routine or sponge napkins - various / greg wilson
Coin in bottle etc.
Why not check out some of the promo videos on the magic dealers web sites (links on the Café) as a lot will depend on the kind of stuff you like performing, and skill level. I sometimes check out tricks on youtube etc. as it often shows 'less practiced' performances, which can really change your view of a trick!
