Thanks Abacus.
Wersi are great sounding instruments and I know which dealer sells them in the UK.
I've already spoken to them and got all the information I need. I really like the Ikarus but for me it's too expensive for what it is and the dealers will not come down in price for a cash payment either.
I've got a great deal on a Tyros 2 with speakers and stand and having already played it I'll be more than happy with it.
If I sell my SD1 then a Wersi may be on the cards for a purchase next year, but since you don't see Wersi in the UK it puts me off regarding support if its required.
The Tyros 2 is also the first 61 note keyboard I've purchased for years, will take a bit of time to adjust to less keys lol
