I've had generally good experiences w/ Riverbed's Steelhead as well as Juniper's WX Series product. For certain types of applications, like email and database replication you can expect to see pretty dramatic reductions in throughput because of the technique of replacing symbols for otherwise long strings of repeatable characters. Also because of the local proxying abilities with regards to TCP ACKs and such, you can also get better pipelining of traffic... As far as whether they are worth the price, this really boils down to a proper Cost/Benefit analysis, but most of the ROI calculators show a return after as little as just a few months.
