i bought 90% of my consoles brand new and some at a cost like the ps2 that i got on import at a price of £800 and my Dreamcast again on import at a cost of £700 but both worth it. i did buy an English Dreamcast from a car boot for £5 so that’s my bargain buy.
i think the bet was to get a retro collection is to first never sell you consoles but if you want to start from scratch check out car boots as you can see if the machine is in good condition and could get a better bargain that things like e-bay.
