Konova slider ad - K1?
 

There is an 80 cm Konova slider advertised locally (eastern Canada) for $60. The pictures seem to indicate a K1 model since there is no bubble level on the slider (the Konova website says the K1 is the only model without a bubble level).

I have two questions about this item:
- Is a K1 model still good? Their website says the rail width is 38.27 mm (all newer models are over 46 mm), and the bearing arrangement is linear (all newer models use a triangular arrangement). Also, I would like to keep my options open in case I want to upgrade it (a crank arm, maybe even a motor). Not sure if this model is upgradeable, though. So, is it worth getting this older model?

- Is the price good for an older model (with no carry bag, no leg pouches, and no adjustment tools)?

I've sent a couple of emails to Konova themselves, but no response so far (and their website is not the best organized one information-wise). So I'm reaching out to any Konova users here.
