I have a couple of them, the one I use for rockets is the anycubic 4max, amazing price but comes packed like IKEA furniture (have a big table a couple of hours, was a three beer build for me) amazing how flat a printer can be packed.

What I wanted (4max had) was,

 * 1.75 filament standard
 * enclosed box (important for large prints and to prevent warpage)
 * stand alone with display (SD card)  NOTE only works with a 'real SD
   card' adapter with a micro doesn't work for some reason.
 * 260 head temp
 * direct drive not 'pushed filament
 * head moves x and y, table only moves in Z  Really good for larger or
   taller prints
 * heated bed up to 100C (important for nylon)
 * low cost (this was delivered for less than $300)
 * Filament detector (detects if filament runs out)
 * big build size ,the working size is 210 x 210 x 300 (tall)
 * Stable table (firm mount, not a fan of the 'spring loaded' tables,
   on thing i don't like about the Ultimaker I bought for work)
 * fan and duct for laydown cooling
 * hack able (I usually modify things like this), easy to change
   nozzles, all of the parts use 'aircraft fittings' able to replace if
   needed. this is a plus.
 * did i mention it was less than $300 delivered

Thinks I don't like about

 * ok quality (Ultimaker is a better build but 6X the price!)
 * it is a cave in the box only light comes from the front door and
   small opening in the top (dark hard to see)  I added LED strip
   lights inside the enclosure to fix that.
 * Single extruder (dual would be nice but hasn't held me back for
   rocket projects
 * belt drive (my heavy duty machine is all lead screw drive)
 * always want a bigger machine
 * customer support........ maybe...
 * not auto-leveling, having said that, the table is VERY stable seldom
   requires leveling.
 * tip / nozzle cleaning brush would be nice, I plan to 'hack one into it
 * control board lives in the box, picks up dust and heat from the
   build plate, I might move it out of the box.

I have run over 30kg of material, (20kg at least of PETg), other than changing nozzles (a few times), a fan that is making noise (have the $3 replacement haven't put it on yet)  and some 'screw tightening' it has worked well.

I know that quite a few ROC members have 3D printers, and that there are a ton of options out there. I'm thinking of buying and/or building one for myself, and am looking for advice.

What models currently give the best bang for the buck? I'm thinking of using one to make small project enclosures for my own electronic projects, as well as altimeter sleds for rocketry use, similar to the ones Mike Kramer designed (and I'm sure lots of other cool uses will present themselves as soon as I have one).

I'm looking to spend as little as possible for a useful machine I won't immediately regret buying. If there are "must have" features, or common problems that are solved by slightly more expensive models, I'd like to know that....

Basically, with all the collected experience of ROC members doing 3D printing, I'd like to know what machines you wished you had bought when you were starting out, instead of what you did buy. Help me learn from your initial mistakes....

Thanks in advance,
