kelkoo has toppies starting from 230.
I think it depends on what you want. The USB on the humax is not as good so if you want to shift programmes on to PC a lot I'm sure downloading the files twice and then running error correction would very soon pale.
Likewise toppy is the only one with TAPs so you can customise the GUI, and add features. On my toppy I have a screen saver that kicks in if I pause the program, a flashy archive menu and an advert jump. Others have TAPs that automatically record programs based on search strings, different EPGs etc.
www.toppy.org.uk will answer any toppy questions.
Also, some 9200's seem to have noisy fans where as the toppy has no fan.
Your money your choice but I'd choose the toppy again.
