HOw do these compare to valentine and the other detector i always hear about on here?
budget
high end
compare the graphs between the two articles appropriately. No one really uses X band radar guns anymore so you can pretty much disregard that aspect. Ka is the newest band, in CA the CHP AFAIK uses only Ka guns. Range in flat terrain on the express series is about half of the best detectors on the market, but still very usable.
The 910 and 920 are considered equivalent in peformance, the main difference is features. I think the main feature difference is the 920 has voice alerts, 910 doesn't, but I am not 100% sure. The 910 is available at amazon for $85 with free shipping in case anyone needs a second source.
I've used both the 910/920 before and they are decent. I've had them pick up a CHP Ka signal about a mile away on the freeway. Their main weakness is they false a lot. The Bel Vector series have better signal processing and reduce false alarms.
