well the Lotmaxx sc-10 shark - looks like an ender 3 clone and is a kickstarter project - so not available to actually purchase and own yet.

On principle and experience I'd advise against most kickstarter projects.
They often take a long long time to arrive, if they arrive at all.

bear in mind that a kickstarter 'purchase' is NOT a purchase at all.
You are giving the company money with no actual guarentee of any good in return. It's almost a charitable donation.

Yes I have 'bought' a kickstarter printer that never arrived - and I'd actually waited until the campaign was finished and the machines had started to ship.

But it's mainly because it's not an actual buyer-seller transaction. You are simply gicving money to someone with no legal guarentee that you will ever get anything in return.
