Matt's appear either Win98 only or "email me if you want one for Win XP" and though it's difficult to determine accurately or easily from the info presented on his website, therefore presumably not PIC Denis? If so, different 'fish'.
PIC is the only way to go.
As for it being only USD$16, you overlooked Matt's vague "Shipping is included in the price (international orders are more)!!!!" Pig in a poke shopping is about as much fun as buying used bridges.
I appreciate your buyer loyalty and patriotism, but Matt's site presents
relatively as amatuerish, US order only orientated, with too many vagaries unanswered upfront posing questions and emails required to resolve - and to save a paltry couple of AUD if even that! Measure twice cut once.
And although it doesn't affect our particular inquirer, Matt doesn't do a JR interface, whose presence locally outnumbers Futaba by around 9:1.
http://www.rc-electronics.co.uk is certainly not the only show in town, but it's arguably the best. Upfront international buyer friendly, Oz friendly, PIC for FMS, JR friendly, immediate, precise and pain free to use at an equitable cost.
Ultimately it's up to the buyer to choose, and I'm glad you're as happy with the product you sourced as I am with mine.
