Frankie,
I thought I posted something here, but it doesn't seem to have shown up. I thought the PSR-620 was equipped with Digital Drawbars, but it doesn't have them.

I also was looking on ebay for the UK, and I found this:

http://cgi.ebay.com/KORG-i3-/150526764445?pt=UK_MusicalInstr_Keyboard_RL&hash=item230c18259d

This is the original Korg i3, or Interactive Arranger, the granddaddy of my PA80 and PA800 arranger keyboards. If you can get this, this will be leaps and bounds above your PSR-620. The sounds and backing tracks were really, really good for it's day. In fact, this keyboard really took the concept of 'Arranger' keyboards upscale, to the level of almost pro, and a lot of pros did do composing on them.

If you can afford it, or are near the area, I would take a considerable look at getting this.

If you have some funds laying around and want to invest in a better keyboard, you might look at the Korg PA50. This is the slightly smaller brother to the Korg PA80, and does not have digital drawbars, but is a great keyboard.

All the songs on this page, down to where it says PA800, were created on the PA80, which has the exact same sound set as the PA50, except the drawbars.

Personally, I would just about kill to get this one:

Oh, by the way, can you tell I like Korg?

The forerunner to the PA800, and smaller version of the PA1X-Pro. A great keyboard, and a good price, since it was over $2,000US.

I had this as my first keyboard

The iX300 was the step up from the i3, used the same sounds as the M1 keyboard and was a great sounding keyboard.

Anyway, I'll stop bombarding you with new keyboards. However, I do want to say that any of those keyboards will be a step up from your PSR-620 as far as sound goes, and they're all good keyboards. The PSR-620 was a top keyboard in it's day, but as you can see, for not a whole lot of money, you can move upstream some.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
