Depends on what you are putting on the SSD. The ideal arrangement is to keep the OS and programs only on the SSD and most, if not all, data on an HDD. Unless you are frequently moving obscene amounts of data at a time, you don't need the speed of an SSD for data so it really isn't cost effective to use an SSD for data storage. If you can keep your OS partition (including programs) down to 90GB or less (and don't anticipate need more someday), you don't really need a 256GB SSD; 128GB is plenty; most people don't really need more than 30-40GB.
If you can afford only one drive, period, right now then get the 1TB Blue for now (right now, that size Blue is a bit faster than even the Blacks) and put your OS on its own partition. You can always get an appropriately sized SSD later on down the road. If you can swing both and your OS and programs don't need more than 90GB (and you won't need more later), then the 1TB Blue and a 128GB SSD would work just fine.
When buying an SSD, you would be wise to avoid ones that the size ends in 0, such 120GB or 250GB, and ones that use a Sandforce controller. It would be better to wait on the SSD until you can afford a good one than to get saddled with an inferior one. I personally recommend the Samsung 840 Pros (just stay away from the 840s; they aren't the same). The Sammy Pros are in the top two or, maybe, three for speed, reliability, and life and are well worth the added expense. Keep in mind you can always just get the 1TB blue and use it for now until you can afford the better SSD.
