yah Nailtique is good stuff, pricey though - its like 20$ ent?

Try ORLY - works much better than Sally Hansen, and most of their products are around 8-10.00.

Orly Professional Strengtheners: Calcium Shield® Nail Armor® Nail Defense® Tough Cookie®

I use the 'Nail Armour' ("Liquid silk nail wrap strengthens nails while Ridgefiller smoothes the surface for a flawless finish.")

and 'Won't-Chip' - ("Orly's super bond forms a tough polymer shield that gives manicures protection and shine. Helps prevent chipping and peeling for up to two weeks.")

here's a few you might like:

"Nail Defense" ("Protein and gelatin enriched to fortify weak nails. Bonds nail layers together, sealing the free edge to prevent peeling and chipping")

or "Tough Cookie" "(Strengthens soft, brittle nails with unique compound that slows keratin breakdown so nails grow long, strong and smooth. Unique formadehyde-free formula contains okoume tree extract.")
