I was the one the rec'd the AF peelables - allergy issues with normal stuff but no problems with the peelables.
I know they don't last long (even shorter times if you get your hands in water for any length of time), but the ease of use is amazing. They have lasted me up to a fortnight on my toes if I use topcoat (I like the Sally Hansen ones, Megashine and Insta-Dri - as they dry through all the coats in minutes).
I love using the AF Brit Black as it makes the glitter coats really pop. If I use holos, the SH topcoat brings out the depth.
I've used the peel-offs for donkeys - Lancome in the cute round bottles and loads of colours was the first. L'Oreal had a small range of colours. Maybelline (and Lancome) had clear versions that were great basecoats for any colours. I especially loved them as they completely stopped any kind of staining.
In my quest to find new colours (the AF range isn't very big, unfortunately), I found a range called Suncoat and also came across a few ranges from Korea on eBay. I'll still be looking into the OPI range, though.
