Why not use the internal renderer? (Even in stable this should give quite good results.)
You can also use blender to get truly wonderful renderings. (Use the VRML export found in pcb_new and import that into blender. Then play around with lighting and shader option to get the result you want.) In fact you can use any artistic renderer that supports vrml (=wrl) version 2.0 as an import option.
If blender is too much work but stable does not give a satisfying rendering, you could use a nightly build as a compromise. (As suggested by @kammutierspule) But to be honest i would not suggest any new user to go this route as the latest nightly builds have a lot of undocumented features, come with a completely reorganized lib that is not yet fully finished, still has some bugs, …
See FAQ entry Is it a good idea to use a nightly build version?
