Don't give up, mate, but you might need to adjust your expectations and timelines. If you want a good one at a cheap price, you'll need to sit back and wait for the right one to come up; that's what I did with my Ferret, but it did take almost 10 years... A similar thing happened with the Saracen, looking for about 4 years and then the right one came along at a very good price.
If you want a cheap one, you'll need to settle for something that needs work and, to be honest, will cost you more in the long run. Your best bet would be to keep saving and then buy the best that you can find, if transport is an issue, you'll need to save for that too.
Owning armour is fantastic though. It's like being a kid on Christmas day, only all the time
Cheers,
