yep...agree with all above...downloads are a very unreliable way of judging quality.....all listed are wonderful creators...as I'm sure are many more who are unmentioned.....people's tastes will also differ greatly...
I will say...I use Javier's alot...as they are related to many of the skins I use....and are just incredibly designed.....a talented guy...
I'm sure everyone will have their own specific criteria....and it is interesting to see all the different designs...and how flash some are....but for me, when it comes to keeping them to work with...they have to be very usable...not too distracting....and a fine highlighting stroke line for wordprocessing use...
