Once you price it out though it's almost the same thing, at least for the 64GB drives and the 120ish GB drives.

Use software RAID instead, and then the TRIM commands will be passed down. Keep in mind that unless you have a dedicated RAID controller, and I’m not talking about the junk on consumer motherboards, that software RAID is going to run just as fast, particularly RAID-0 and RAID-1, where there is no CPU overhead for parity calculations.
There are other benefits to software RAID too, namely that you can take those drives and plug them into any other system and the RAID’ed partitions will be usable without being tied to specific hardware implementations.
