I hope this one sticks, so I can eventually afford it.
I always use older technology, because I wait for the price to come down.
For instance, my PDA is a Sony Clie. Originally it was about 200 dollars, but I got mine several years after it was released, and it only cost about 40 bucks. I also got the little camera that hooks up to it for 12 bucks. It was originally over 100. So, my little 300 dollar PDA only cost me 52 dollars.
Hopefully, if I'm patient, I'll be able to get a Headplay system for about 100 in say maybe 3 years.
