You may be able to find it in some stores a bit cheaper, but you can get the Game of the Year edition (with the *great* Team Fortress Class online add-on) for $30 at www.ebgames.com.

Half-Life: Counterstrike is also available as a standalone game for $30. That also includes TFC.

The Platinum Edition is rather expensive at $55, but it contains *everything* for Half-Life outside the Blue Shift expansion. The whole Opposing Force expansion, Counterstrike, Team Fortress, a bunch of other mods, plus the full original game.

If your connection is good, the Game of the Year edition is good for $30 (or you can find the original in some stores for $20-25), as both Counterstrike and Team Fortress are available as free downloads. If you've got the bandwidth, you can save some bucks by just downloading them ... and, of course, Day of Defeat. Also free.
