What is the best feeling in Modelling?

This is a very random question, but I would say for me (apart from the obvious peeling off a successful mask) is buying a kit that I have been wanting for a really good price, or getting a model show steal. The second one happens pretty often, as last year I managed to get Tamiyas 1/20th Lotus 102B for £35 with every everything sealed and still good quality decals, and I have seen many on eBay for at least £55. At Telford last year I also got Eduard’s Camel and Co set for £25 whilst at most places it goes for £40-£50. Not so long ago at the Southwest model show I also saw Tamiyas 1/24th Mercedes Clk Gtr full view for £40 while many listings are £100 with most going for £65+. About my first point, I got ICM’s Nakhon Phanom airbase set with the B-26 (or A-26, I forget) and the Cessna for £74, but the regular B-26 was £75. I anticipated this kit and I was happy to get it. What is the best feeling as a modeler for you?
