Both mine are clipped (see this thread
http://www.cockersonline.co.uk/discuss/index.php?topic=27587.0 for pics of Zorro who I just did at the weekend). I'd love to have handstripped dogs but Bella's neutered and her coat is thick and woolly since then, lots of matts and is so much easier to deal with if she's clipped. Zorro is being neutered this week so I'm just resigned to having two clipped cockers.
I think if done well it can look nice, and if your groomer knows what a handstripped cocker should look like then I'd imagine he'll probably do a good job, not too short and a bit more natural looking (which is what I've tried to do on Zorro).
It is much easier to look after them grooming-wise if they're clipped, I just give Bella a 5-10 min comb through of her feathering each evening and a soft brush over her back and that's that. Before she was clipped it was taking an age and wearing patience thin on both sides...
I still prefer the look of a lovely handstripped, un-neutered cocker with that lovely silky coat though...
