I dream with getting one from these guys.

The best-looking suit is the suit you like the look of the most.

As for some makers

Onefurall (Various styles) http://www.furaffinity.net/user/onefurall
Mixed Candy (Various styles) http://www.furaffinity.net/user/mixedcandy
Don't hug Cacti (Toony etc) http://www.furaffinity.net/user/donthugcacti
RadyWolf (Japanese style) http://www.furaffinity.net/user/radywolf/
Beastcub (Realistic style) http://www.furaffinity.net/user/beastcub
There is also B3Mascots/Joecifur if he is still around, and he does reasonably affordable toony style ones.

htfcuddles above my comment linked to Radywolf too.

In the end, it depends too on the style you like. Some suit makers do realistic, some will so super toony etc. I personally love the "look" of Onefurall suits (how can you fault this mug? http://i.imgur.com/m1jjmPs.png) but they break the bank ($2000-4000 and up). MixedCandy does some very nice ones as well.

I bought myself a Noblewolf suit as my first suit since the then-exchange rate was insane and allowed me to get it at literally half the price everyone else would pay. Quality is average, but I bought it under peer pressure (everyone else at the meet and I were talking about them, and people kept suggesting I go Noble). It ultimately wasn't a brilliant move, so now I don't go by what others tell me looks cool or is the best, but buy what I think is truly the suit for me, esp when it comes to style appeal and stuff.

Quality on all makers is different. Even the $4000 suitmakers will have seams and stuff that come apart, although you could always look for a good warranty, ask the maker if they are happy to take it back and repair it if there are any faults within the first 3 months etc.

Radywolf suits get a lot of praise, and the style is generally liked, although I have -heard- that warranty and whatnot is not very good (ie if you get an issue with your suit, they will refuse to do anything with it).

 patrickthedog dos nice fursuits, but the best is to be in europe [she is from poland]

You can always check that fur suit review group here on FA to learn about the makers craftsmanship, quality, and communication skills.

I always thought that sunnyvalleycreations made some of the best ones, but their hands/heads/footpaws are pretty massive compared to other suits.

I would add DTWA and By Cats 4 Cats.

I own as I own an otter partial and a digitigrade badger suit from DTWA. Ashley is great to work with and I am very pleased with both suits which fit properly on arrival with adjustments needed. Her prices are reasonable and turnaround time is 4-6 months. Top notch quality too.

Snap from By Cats 4 Cats has great customer service and he does wonderful 3D eyes. He is a pleasure to work with as well. My plantigrade badger suit did need some adjustments but he reimbursed me for the return expidited shipping and added a zipper in front at no additional charge.

Both have my highest recommendations.
