Re: No, you don't wish you'd have bought it.
or you'll finally decide to take that useless piece of junk you haven't touched for 10 years to the tip and go through with it.
the following week something will come out of left field that would have been so much easier with the device you just threw away. It's happened to me every single time I had a clear out.
or you'll get rid of a niche device because you can't find the interface cable / 13 volt power supply anjd thart missing part will turn up the day after you have skipped the kit.
