Allbion and Arms&Armor are two US producers with a lot of variety. Valiant Armoury offers some good values of swords with scabbards and less costly than the others Darksword is popular with some, as to the packacges. Museum Replicas actually fits the bill for budget swords. Del Tin of Italy are quite good for the money.
I would browse Kult Of Athena to see a lot in one place. If it is meant as an hierloom, the Arms&Armor Edward III sword is quite pretty and very functional. Here is one getting a high class scabbard.
One advantage to Arms&Armor is they work with folk as to possibilities. I had owned a one off from them that has the Edward III blades and their Duke of Urbino hilt. It has been a fine sword and was modified by the current owner to have a longer hilt. Again, this is just one possibility.
It really is a matter of choice. I have spent time with the Albion Baron and it is a fine sword. The same friend that now has the EIII blade mod has had a Baron almost from the time he traded into that old A&A sword.
Of two other A&A swords I have owned, both the Black Prince and German Bastard have always been a pleasure to own and use. I had ordered the Black Prince with bronze and now belongs to another that did it with a blue grip. I am trying to trade the GBS back to him for the BP.
The A&A GBS with some more great big swords A Conyer's falchion and two Del Tin bastards.
The Del Tin 5157 (about $500) is longer than the Baron and other big swords at 51" while remaining about 3.3lbs On our right here with an Old pair of ATrim XIIa and XIIIa. It is longer than the A&A German Bastard.
In the end, spend some time window shopping and reading reviews. For an Arthurian period sword, I would think some centuries earlier to regard a spatha or even earlier migration era sword.
