I'll add to the endorsement of swordforum.com and netsword.com
On swordforum there is a links section which should point you in the right direction. They also have a quarterly E-zine that includes reviews of words.
As with knives, you should decide whether to buy production pieces, or custom. The good news about buying swords is that even high quality, hand forged customs can be had for a few hundred dollars.
For production swords, I would not accept quality less than that of Del Tin. They make fairly good copies of real pieces. There are many dealers and they go for $250-$400
You can get a custom for $500+/- from the following sword smiths.
Michael "Tinker" Pearce, who makes stock removal, differential tempered swords:
Or Jim P. Hrisoulas (JPH), who makes forged, thorough tempered swords:
Both have a reputation for swords with outstanding performance.
