My yearly budget is £0 if that's any motivation. I have a mortgage to pay and two teenagers and a small child who are like locusts when it comes to cash and food and don't want to work any harder because time is more important than a salary. Careful balance means I have to get creative elsewhere.
I'd buy another TF930, hold on to it until the other ones are gone and stick it up for £120 BIN. Then I'd keep the TF930 and sell the Velleman counter. It has a TXCO, has external ref input, connects to your PC and goes way past 2.4GHz. Then your TF930 was technically free and you have some cash in pocket.
Only if you don't incur interest however. The zero interest credit card is, if you are disciplined, a good way to make profit with no capital being available. Just keep it away from SWMBO.
Stalking my courier for the TF930 now...
