They can be found on ebay for under $60 shipped. The only info I've come across is that the performance is comperable to sirf 3 or perhaps a bit better. Of note is the baud rate seems locked at 9600.

I have one & it is fantastic. I was having troubles with my bluetooth sirf III, so I decided to get one of these to always get a lock. Compared to my sirf III, which only locked to say 3 to 7 birds if it got a lock at all, this thing locks in 9-12 birds easy & before the computer even boots up. If the weather it really bad, the lowest lock I have had is 7 birds, and never not gotten a lock.

Hmm sure sounds good! Do you mind my asking if you found it somewhere other than ebay? How about resuming from hibernation?

I got the qstarz 818 bluetooth GPS and it has the MTK chipset.

Now I've never used sirf III gps before but The MTK compared with my garmin c320.....the difference is night and day. Definitely very sensitive and locks on very easily and effortlessly. Highly recommended.

I just got it on ebay, shipped from Hong Kong. By the way, the driver was a little wonky, and not MS certified, but once I got it going, no problems.

I just also ordered this probablly from the same guy on ebay in Hong Kong, Will this work with iGuidance? or is there a better GPS software for this?

I use generally it with iguidance 3, roadrunner & google earth under xport3 com splitter.

I took my MTK GPS through a tunnel under the Fraser River today. Amazingly enough, I still had 5 satellites locked in about 1/3 of the way in before I lost the lock. Even then, it was still detecting as many as 5 satellites (without a location lock) in the middle (under the deep water!) at the worst. Simply amazing!

Can anyone confirm that it's actually functional?

And what the hell does this mean:

6) How to use the 5Hz update rate function in the FGPMMOSL1?
We suggest customers if you need to test 5Hz update rate function, it is much better to be done by GTop Co., not by the end user, in case avoiding some potential risk and problems.

I been using this GPS unit for a week now. I must say it works great. I make this unit number one out of the past units I have owned(BU-303 & BU-353). Quick satellite lock, and all. I notice better accuracy when using IG3 as well.

The units height of the unit is a little bulky, and it doesn't seem as weather proof as competing units, like the BU-303 and BU-353. Still worth the forty eight bucks I paid on ebay tho.
