Another option if you are running tight on funds, another track saw option is the Grizzzly/Shop Fox/Scheppach/Wen track saw. All are the same saw, just different colors. I am sure they are not the same quality level as the Makita, DeWalt, or Festool, but fits in many more budgets like in my hobbyist budget. And a quick search on YouTube shows people making some simple tweaks to these saws to improve usability and dust collection.
I have done fine for 35+ years with a good straight shop-made guide and a good circular saw and GOOD blade, and with my current setup I can split my pencil marks and make build ready cuts. However I just picked up my new Wen track saw yesterday, and the biggest part of the decision was for the dust collection. When I use my CS and guide outside, it does not matter how must saw dust is made, the leaf blower takes care of the mess. But on a rainy day or in winter time, I can't work in the shop without covering everything with sawdust. Have not even had the time to set it up and test it out, that will be a weekend project and hopefully THIS weekend...
I was able to get into the whole setup for the $400 MrSkittle has budgeted. $171 out the door for the saw kit, then another order for a Freud blade, two 55" Shop Fox tracks, track connectors, and the DeWalt track quick clamps.
The Wen saw also comes with two 27.5" tracks, good for shorter jobs, and track joiners to make one 55" track, the others are for the saw only. I plan to add a 90° cleat to one of these tracks for quick square cross cuts.
