I got them from
http://www.surreypetsupplies.co.uk , £93 including P&P, that was the best price I could find. I figure I was paying £30 a shot for not very good groomers so I may as well do her myself and hopefully over time will learn how to do a good job.
I'm leaving her feathering (just thinning it when it needs it) so it'll be her back, head, tops of the ears and her throat. I keep looking at pictures to try and work it out. I've never been able to find a groomer who wouldn't either leave her body completely alone or clip it really, really short, so it's nice being able to do it myself (in theory) and get it to a tidy but still cockery looking length, if that makes sense!
I do think her being spayed has made her coat thicker, it's still nice and silky but doesn't lie flat, around her collar it all sticks up all over the place like a little ruff and then the back end is curls a-go-go... It's a shame though as I never wanted to clip her really but I prefer the fact that she does at least look tidy that way...
