I am not a Beatles collector: there are, however a few web resources that may help:

There was another site that is now gone.
For fun, you might look for a German Horzu Die Beatles -2 stereo. It was a two track sent to Germany for a special release connected with a magazine, and it (mistakenly?) contained no additional mixing or reverb. So, you wind up with hard panned L and R, unadorned early Beatles. There were a couple issues of this anomaly, i put it on occasionally, but there were also "correct" mixed copies bearing the Horzu label so do your due diligence. I’m operating from memory here.
I think an early Blue Box from the UK and that recent mono set are both really good values unless you are chasing early tube cut copies; some of the deadwax in the occasional blue box sets BC-13 will have tube matrices, I’m told, but that’s hit or miss, it was really whatever was in production at the time- still good though. Many of these sets were bought or given as gifts-- and often were rarely played.
You should probably search through the Hoffman forum- there are people there who make the Beatles a religion. And, I do know a dealer on the West Coast who only specializes in first pressings--his name is Jeff Gold, he’s a nice man and has found some pretty cool stuff over the years. He’s also published at least one book but it is not limited to the lads. [url]
