I'm in the same process, but being a lazy <insert suitable expletive> ... I'm using KeyVisa.
Darren acknowledged my payment on 5 July, today (13 July) I got notice from VFS that they have forwarded my application to the UK.
It remains to be seen how long the process takes.
As an aside I applied to renew my UK driving licence on Wednesday last week (using my existing PP number so no need for a new photo), paid my 14 squid using my UK credit card. The new licence arrived at my (ok, my parent's) UK address on Saturday! I have no idea why it was so quick, some of my UK friends have been waiting months.
