Great idea for a thread. I've had a lot  of great buys but i really think my best was a pair of Spica Angelus for under £100. Only six pairs ever shipped to the  UK and two definitely no longer in use, I sold them when i left the UK for 18 months but I Wish I'd stored them.

I also got an LP12 for £50 but it's a long time ago.

Worst? A "Linn LP12" lid in "Mint Condition" that turned out to be from some cheap Japanese deck. It had two cigarette burns and had been scratched all over with something like the end of a key.

Great deal on the Mirage speakers. A good friend living in Camden had a pair of those to replace his Acoustat 2+2 and they were a very musical speaker.

Obviously for me the Nakamichi Dragon speakers were the best eBay Hifi acquisition. Worst: not sure really, nothing has been a disaster although I did fall for a used Siltech cable at silly money that, whilst genuine, had been badly butchered and poorly re terminated at one end which made an apparent bargain rather less so.

I did get another great bargain with another Siltech cable that was on EBay.com in the U.S. Owner had bought direct from Siltech main dealer in the Netherlands and had it shipped to US. Those nice people at US caroms could not believe that the fat bits of insulation were not full of drugs so they had made several small cuts into the outer insulation to look for white powder. Fortunately they didn't do any structural damage but the owner didn't want this cable in his otherwise pristine system. I bought the cable ( signature level FireWire with list price of $2000) for $150 as the only bidder. Still using it on the DCS FireWire network

Best: selling my modified BMW M-Sport 335d Coupe on eBay. Couldn't be happier, went for a decent price, buyer turned up to look at it and paid the full winning price. A very easy deal. Put paid to ever wanting to use Autotrader again.

Worst was buying a small TV I wanted for the bedroom. Seller, who had sold it as in the UK with free postage, turned out to be in Holland and tried to add a substantial charge for shipping it to the UK as he was no longer coming over to deliver it. I refused and he started calling me names, getting really shirty. Tosser.

Ah, if none Hifi stuff is allowed, then worst without doubt was a Matra Simca Rancho I bought on eBay. Collected at night from a bible thumping religious nut. Deal done at Aust services by the Severn Bridge. Biggest load of junk ever. I only bought it to take my two German Shepherds to the woods for their regular walks but they had too much sense to get into the clapped out rust bucket which I had to pay the scrappie to come and take away.

I wish I had! Got a friend who is restoring a Matra bagheera which has the same eccentric build quality.

Everything ive bought ended up in the bin   Only kiddin'. I think a couple of cassette decks have been keepers the rest did not reign long..

You might laugh at this or on the other hand think im insaine but When im bord with something or really cannot be bothered to sell it on it take it out with me on my way to work in the morning & place the item in a public ginnel at the back of our place. always guarenteed that someone takes it..Someone got a loverly mint Ferrograph Series Seven R+R a few weeks back.
