I do mostly just vacuum purged bho right now, without reclaiming because the amounts are so small. You can grab small tubes that hold maybe 10-20 grams or so at headshops or online these days, and of course the now time-honered stainless steel turkey blaster apparatus (they both fit the nipple on canned butane). $10-20 depending on what accessory items you have lying around the house, and no weird looking devices necessary. Safety is the big deal of course, outdoors only, no sparks, not for idiots or intoxicated folks, etc. Don't get lax or shit will blow up (always pass on the lecture when answering these questions). Anything bigger and reclaiming makes sense, check posts by Greywolf for relevant threads and geniusing. And I don't really like iso much, although no expert on it, always seems to have off flavors and flat effects, I'm spoiled by butane which is super clean for such an easily available non-toxic solvent.
To me, mechanical extraction like sieved hash and kief can be potentially richer as a connoisseur product, complex layered flavors with trichs more intact, things you can really taste with the right vapor apparatus (but of course those have more than just pure cb oils). On the other hand, good bho/wax can be really flavorful too, and it offers advantages like the option to remove more impurities for smooth operation in a pen-vaper, or even process further for patients who want certain effects over others.
