No need to denigrate the efforts from Nicholas Pike and his unit's link to RepeaterBook. Yes he does use a Bluetooth from a Chinese source (The source of most Bluetooth serial chips anyway), but he has done the work on integrating these into HIS RepeaterBook for those who want to be able to automatically download the repeater setup to their compatible radio. He has put a great deal of time and effort into this overall product and it is a great resource for the Amateur community.
If you look at the price and the need for each step to at least cover their costs the $50 is, in my mind, justified and not out of line with the VE2DX cost of $50 + $15 shipping with no ability to upload Repeaterbook settings.
Bu the way the basic speed of these Chinese chips is 9600 baud. The standard speed of the BlueCat is also 9600 baud, just like the VE2DX unit. My guess is VE2DX uses the very same Bluetooth module as the BlueCat under it's black plastic case. Perhaps a better Mini-DIN plug, perhaps not. While the BlueCat uses a cable on the dongle for more flexibility in locating the device the VE2DX unit is directly pugged into the port and may be hit and bent in use. Your mileage may vary.
Nicholas worked with me to build a RS-232 Bluetooth interface for my TM-D710G and was very helpful and cooperative throughout the process.
Support the RepeaterBook as you can make a donation on the website or perhaps buy the Dongle from the UK distributor.?
I am sure the VE2DX makes a nice interface (without the RepeaterBook link), but going out of your way to call the BlueCat "Chinese Junk" is unfair and misleading. It depends on just what functions you are looking for. I have used the BlueCat with my IC-7100 and TM-D710 and it does just exactly what it is meant to do.
If you want to buy a BlueCat they are available from :
