Tektronix Tds 3014b

Hello all this is my first post and a newbie to the electronic world. I am in the process of buying a used Tektronix Tds 3014B. Only thing is i can not find much info about them or anyone on youtube using them. Not sure of the age either. Are they any good or just to old nowadays. Im picking it up for £250 is that a good price? Any help would be appreciated.

There's lots of information about the TDS3000 series out there, it's a very popular scope and if it's working properly and in good shape that's a fantastic deal, even a broken one is worth that. These all use the same hardware so you can do a simple hack to upgrade it to the 500MHz TDS3054 for free.
The only real issue these have is the DS1742W NVRAM/RTC is reaching EOL for the internal battery so at some point you will probably find that the clock stops updating when the scope is off and then eventually it will start losing the other settings too. It's fairly easy to carve out the old battery and wire in a new one, or I made an adapter board recently to fit a still available DS1744, just waiting for boards to arrive so I can build one and test it.

So they are the same being a 3000 series. I wasnt sure as there are all different model numbers. Well i might be able to find some stuff now. Thanks for your reply and hopefully everything is good with it and i can start to learn some things.

TDS3000 is the series, of this there are multiple sub-models. TDS30x2 models are 2 channels and TDS30x4 models are 4 channel. The 'x' digit is the bandwidth, 1 = 100MHz, 2 is 200MHz and so on up to the top of the line 500MHz TDS3054.
Actually I think the B series has a 600 MHz TDS3064 which you should be able to upgrade yours to.
