Last but one time I tried to buy a keyboard from PMT was when they went through their 'lets not put prices on things so people can't compare us with the internet'. There were no staff around, I looked, they had a DX which is what I was after, but no price. So I didn't bother, I just assumed it was because it was way overpriced. I found out later they were equal to the best price, so I would have bought it then.
Then next time I tried to buy a keyboard from PMT, again, there were no staff around. The Argon i was looking at was there, it took a while to wrok out how to get sound through their mixer, and I quite liked it, but I had a limited time, and it was loud with other people playing so I didn't get it. I got it some time later. I don't remember who, may have even been them.
Wasn't good either way.
Soon after that they moved (the bristol branch) to a place where I would have to go out of my way to get to, so I simply don't get there any more - bought my ME90B from there as I was going to bristol, I knew I wanted it and it was worth stopping to pick it up so I could use it that day.
