DoubleTalk LT, LiteTalk, Q-Talk

[Debee Norling]

Can someone describe what's different between these three synthesizers. They
all are advertised as running on batteries and being small. DoubleTalk LT
and Q-talk can both be easily bought online, but I can't compare prices
because one is American and one Australian currency. And what about the
LiteTalk? Is it still available?

And it appears all three are based on the same RC Systems chipset, is that
right?
