Auctions like this are sometimes interesting, makes me curious as to what something is worth in someones elses eyes.
Not judging anyone, what a person's willing to pay for something is entirely up to them and they'll have their reasons that I can never know.
But there's also the question of what use they'll be put to... may not necessarily be a collector that's bidding.
Then there's who and how they're bidding, which can also be interesting - take a look and see what you think.
Easy but not cheap "upgrade".
Could fill in anything on the "DIY" spec plate ;D
