i just bought a 205. i already have a HRM and dont like wearing that one, so might as well not spend extra money on the 305. the 405 wasnt out when i bought mine.
i got it from
Amazon, 149.65 total thanks to prime shipping.
i really like it, i only use it for running.
the negatives i have found so far though:
- sometimes the pace is really wonky. i will be going THE SAME pace and one second, its 14:12, the next its 26:15 ... i KNOW i didnt slow down that much in the course of a second... not sure if it has to do with satellites or what..
- i have yet to find a 'quick' start that you dont have to set a time / distance cap. my first long run, i set for 45 mins. 45 mins into my run, the garmin told me i was done. well that's fine, but i was about 8-10 mins from my house... wish there was a way to just GO... (maybe there is and i just havent figured it out yet???)
despite those 2 things, i love it and wear it every time i run...
if i had to do it again, i'd probably still get the 205 cause the wheel on the 405, i dunno .. reminds me of the iPod wheel which is really sensitive and i always pass what i want to select.
