DTN Satellite / Serial Card Alternatives

[ALVIS2JS@xxxxxxx]

Moving from TS4 / W98 / BMI sat to TS2k,V5 / Windows 2000 / DTN sat.

Am considering Pacific CommWare TurboExpress 920.  But DTN rep also mentioned 
alternative serial cards from Boca, Siig and particularly Digi International. 
 Digi (www.digi.com), which apparently has a 60% market share,  claims their 
twin port Acceleport Xr, is a superior product that minimizes use of system 
resources.  At $200 to $250 (street price), it is somewhat more expensive.

Does anyone have knowledge of or experience with these alternatives to the 
920, particularly the Digi Xr.  Any thoughts appreciated.
