Depends on the price, I have some oster power max, they are much lighter than the old oster, I have always used oster as they are very durable and I break everything basically and I love them, but I do groom frequently for clients and they are over £100, I think I paid £125-£130 .
ah! that's the way I was leaning after spying a make on animal 24/7 that seemed to be doing a good job, I think any decent ones are going to be in the hundred pound range. Probably more sensible at this point to send her to a groomer since thats only about 20quid!
