@csucbrown and a few others... You're missing the key points that the op was asking for... He is looking for a sim to practice approaches and holds. The age of the approaches DO NOT MATTER. The whole point is for him to be able to practice shooting an approach or approaches and holds. MSflight sim or even X-Plane offers the best bang for the buck. I'm not heavy promoter of MSFlight sim because I've used it since FS 1.0 and beta tested every version since 4.0 and worked with a few technical writers; I'm promoting it because it is scalable, offers the widest options, and overall balance without hurting the pocket book.
To the OP: go on ebay or some flightsim websites and check out the accessories that can work with Microsoft. Don't worry about the age of the database because you don't need an accurate database to shoot approaches and practice holds.
Years ago I used to fly and log in a sim that was hand built and it used actual flight instruments. There was no GPS, nothing electronical and to this day I remember what the old man told me. He said, it doesn't matter how advanced a sim is, if you don't know the basics and fly the basics, then the advanced is just a hinderence, not an asset.
I would see airline pilots come in and fly his sim and come out sweating and exhausted. So, regardless what you get, make sure you study the basics and practice, practice, PRACTICE.

 

I bet I saved at least $2,000 by practicing approaches on MSFS as an instrument student. The first time I did an NDB approach in the plane (I'd practiced them in MSFS), my CFII was absolutely shocked when I nailed it the first time.

Later when I was instructing, I always recommended its use to my instrument students. Those that used it did significantly better than those that just tried to figure it out in the plane (expensive!).
