can't remember exactly but it's 105k or XX months, whichever comes FIRST. so you are overdue. i guess you want to eat first, but other than that i would do it ASAP.
as far as budget goes, if it breaks you're in for a lot more $$$ because it's an interference engine. it would take a miracle not to bend any valves etc. then you would have to have a head job to replace valves.
btw have the headgaskets ever been replaced? you may want to have them carefully examined to see if you have any leaks before doing all the timing components and then having to essentially take the same things back off.
if you want to keep the car a long time, also consider putting on a new water pump and resealing the oil pump in addition to the timing belt, tensioner, idler pulleys, etc.
A good mechanic could do the job on the cheap and only replace what was needed or felt nearly worn out but if you're going to 200k then at least one of the remaining components will likely go bad before the timing belt needs replacing again. At best you repeat-spend the labor. At worst something seizes, timing belt breaks, ... or water or oil loss not caught causes bad things too. Not very likely before 150k but after that becomes increasingly likely.
