Vic,
Your memory is good! The i30 is gone from the US market. I think you would have to buy one used if you want one. I only have 2 i40m left in my store. The i40 can load i30 styles, but has no pattern sequencer to record your own styles. It has all the styles from the i30 and most of the sounds. It does have the same 16 track sequencer and backing sequencer and over the i30, there is a vocal harmonizer built in and a guitar effect processor as well. The price is much less than the i30. There is still the quarter tone tuning and all the other functions of the i30. The screen is smaller but basically it is very similar. The retail price was $1250.00, you can email me if you would like a price quote.
