If you just want SACD now, and you are on a budget, the Sony DVP-NS500V street prices at about 220$. It supports DVD, SACD, CD, Video CD, DVD-R, and DVD-RW. Its not progressive scan (sorry home theater buffs). But needless to say, its a pretty 'multipurpose' player for just over 200$. I've been thinking of buying it just to get a taste of this whole SACD thing, and to have an actual DVD player (I just use my computer right now). At that cost, I'm sure it doesn't sound phenomenal, but at least you can reap some of the rewards of the new format without breaking your bank, which is important for people like me who have a very fragile bank
If you want DVD-A instead, check out the toshiba SD4700 or SD5700. They both support DVD-A, DVD, MP3, CD, Video-CD, DVD-R and DVD-RW. The 5700 adds HDCD support. It also has progressive scan, which is neat. They street price at about 210$-250$.
Anyway, those are some uber-cheap entries to the DVD-A and SACD world. Certainly not like the top notch players, but they'll give you a good taste of the format.
