Normally, Epson profiles for Epson papers are embedded in the printer driver. To up-date your printer driver (you didn't mention which printer you are using) go to the Support section, locate your printer, then migrate to the drivers and install the latest version, which most likely contains the Legacy profiles.
Many papers these days have similar finishes and characteristics, to the extent that in some cassesprofiles can be virtually interchangeable without it being the case that one paper is simply a repackaged version of another. There could well be subtle differences in the papers' specifications that do not necessarily rule out the feasibility of using a profile for one paper on another. I've been observing this. As for pricing, this whole month Epson has had a rebate program running here in Canada providing customers with a rebated third package cost for the least expensive of any three Legacy (and some other) products purchased. At this kind of pricing it is very competitive with any other offering of its quality on the market. This program seems to have been running from month to month so it would be worthwhile checking with your dealer whether it has been extended for November.
