Hi, I'm looking for affordable seamless textures and ones I can use on 3D models. Can anyone suggest any good places to look? As I have no idea where to start. I want top quality (royalty free) next gen textures, that I can buy and use in commercial/indie games. I'm looking for metal, wood, ground, rock, textures, stone wall textures and so on.

You may want to try MaPZone or Genetica, they make it easy to generate seamless textures.
NVidia has also release a free texture pack : TransmogrifyingTextures Vol. I.
I have come cross some commercial texture packs but I have never used them so I can't recommend any.

To buy your own I suggest:

http://www.dexsoft-games.com ----Great site, limited but quality and well priced. Check out their texture library!

http://www.renderosity.com ----Lots of cool stuff and well priced

http://www.turbosquid.com---- Expensive and mostly useless, search around you may find something

http://www.max-realms.com --- I dont have much experience here (never bought anything from them) but it's been recommended to me.

And of course if you buy membership CGtextures has tiled textures for sale: http://www.cgtextures.com/index.php

http://www.cgtextures.com/ is my favorite for designing buildings and environments. I bet you could also find some textures you can use on character models too. It's free and easy to sign up. (you can only download a certain amount of images per day if you don't pay for it, but it's really not that big of a deal.)

Any texture can become seamless easily, you just need photoshop and about five minutes for simple textures, a little longer for more complex textures. You take your image, apply an offset and get to work on that seam with the clone tool. If your not sure what I mean, a quick google search on tileable textures should get you a bunch of tutorials, since this is so easy to do you'll kick yourself for not trying it out sooner ;)

Especially the latter. If you want good textures, there is hardly a way around Genetica, in my opinion.

MaPZone turns me off, personally, because there are about 25 mentions on the website of the awesome patented technique used in this program (super awesome patented secret technologies are always a bad sign), and yet I'm not able to produce a texture that looks at least remotely the way I want 15 mins after downloading the program.

Genetica, on the other hand, costs money and is comparatively expensive, too (for "just a texture tool"), but it works really well and is quite intuitive. It certainly takes a while to learn all the controls, but you figure out the basics in a few mins.
There is a huge (and I really mean huge) regularly updated library of royality-free photos coming with Genetica too, which can be used for the synthesis tool (or otherwise). So all in all, it is worth its money in my opinion.
