Slider II Vintage Series : This is a really great instrument

Especially when you consider it's a budget instrument. I would say you can't go wrong with this as a good starting point for slide guitar learning. I love it and so glad I went for it :)

The only thing I would say is that I'm going to get the Dunlop LapDawg to go with it, because the bullet that comes with it is a little tricky to hold and I think it would be easier to play with something a bit more ergonomic. But that of course is not about the instrument itself.

Also, it may sound obvious, but if you've never played slide before, do not expect to grasp the feel of playing straight away... The theory of playing is of course the same as a normal guitar but this is a different instrument in it's own right. Just give it time to get used to it :)
