I did a little amateur watch servicing in the past, and I find lens work much easier - at least in terms of handling parts, disassembly and re-assembly (I never had the steadiest of hands, so watch repair was frustrating for me :o).
Before you make your decision to press ahead, I should advise that you really need some basic tools to do the job properly. See this post for a list of my own tools, correct at the time of writing. Of course, you can get by with less, or substitute what you have to hand for some tasks... but it's worth having the right tools for the job. If you think you might use the tools on several lenses, go for it. If you have no interest beyond the one or two lenses you've mentioned here, then it's probably not cost-effective. But since you've already considered it before, I think it might be worth the relatively-small investment :)

I've successfully cleaned affected elements with white vinegar and lens papers (occasionally, freshly-opened cotton buds for stubborn bits), then rinsed the elements off with bottled water and dried them with more lens papers. I've read so many different articles that had so much conflicting advice that I've never been 100% certain that any one method is risk-free or "correct", but this worked for me. Use of cotton buds isn't risk free - there's a small risk of abrasive contaminants in the cotton - but if the lens is otherwise done for, it's worth a shot. The most important thing is to use a blower and soft brush to remove any debris from the elements before cleaning.
Be aware that whilst you can remove visible fungus, there's a chance it may have eaten through coatings and even etched into the glass. If it's just the coatings, then depending on the extent of the infestation, the lens could still be perfectly usable. If the glass is etched, though, it's a door-stop :o
But if the choice is between junking a potentially useful lens or having a go at careful cleaning - even with risks attached - I'd say have a go at cleaning it. You have nothing to lose :)

Tamron's mirror lenses are apparently some of the better models out there, and reputedly capable of good results compared to most. I'm stating the obvious, but accurate focusing is key to getting good results. Live view is essential - OVF focusing just won't cut it. Careful consideration of subject background is also advisable, due to the donut-shaped out-of-focus highlights. But with these observations noted, it's possible to get some very nice images with the better quality mirror lenses.
If I remember correctly, @csa (Carol) has this lens and gets some nice shots with it...
