You can slice the models later and print a puzzle to assemble.
The things I have heard.
Ultimaker: nice, but noisy
Printerbot: cheap but a massive headache
Roestock:depends on vendor, there is a bit of tinkering required to get it working well. Accuracy is best in the center speed is best on the edges.
Bukobot: pain to assemble but after it is together it is a nice machine.
Prusa: get reviews from your vendor as there are bad eggs out there. If you get a good one they are great.
If you are making parts that you want to be strong you want a heated bed as you could print more plastic types, some have higher yeild strength others are more ridged. For the LARP gear you will want to use ABS as it can be smoothed with acetone making it look better and increasing bond strength.
For your purpose you DO NOT want a Rosen printer. The material cost is too high.
