Hello All,
I have an ‘original’ Kickstarter Snapmaker A350.
I would like to upgrade it, now that there is a sale on.
What would you recommend?
This isn’t so much a “recommendation” as just what I did. Calling it a “recommendation” like it’s a good idea would just be confirmation bias on my part. 
I have the Kickstarter A250 with enclosure.
If you have the Kickstarter do you still have the coupon for the half off the fast rails? That plus present sale price (IF they honor both) would be a pretty good price off. I used mine to grab a set but haven’t even attempted install yet, keeping as spares. (Possibly stupid esp if I end up finding out I have some QC issues and I wait a year or more to install them…)
I think the PSU isn’t worth upgrading - just find a low price better external fan yourself to quiet it down. I have also bought the upgraded 3D print module but have it still waiting in the wings, and the 10W laser. That I’ve used and been very pleased with, I just never got comfortable that the 1.6W was doing much (and its seems like their control has evolved better thru Luban).
Had forgotten all about that 50% code. Thank you very much for the reminder!
That saved me €515 on my order. 
Stuff is already on its way.
