The all metal construction of the machine makes it ideal for medium

It also has a heavy duty metal edge guideadjustment knob that makes it easy to line up your documents forpunching. Limitations: In using the CoilMac ECI I didn't really notice any glaringdeficiencies. However, punching paper for large documents was a littlebit tedious and repetitive. For users who need to do a lot of bindingor who do large books I would suggest looking into an electric punch.However, the version of the ECI with an electric punch costs almost$1000 more so depending on your volume and your budget this machine China ppgi corrugated steel sheet maystill be a good fit for you. As I noted above, the coil inserter will not work with larger sizedcoils (probably anything larger than 30mm). However, this is common forintegrated inserting devices. To fix this problem you would need to buya standalone inserter and it still won't do a great job of the largerbooks.

The ECI is also not ideal for scrapbooking and other highlycustomized applications that use odd sheet sizes. The disengageabledies on the ECI will work great for punching standard sheets but arenot flexible enough to punch fully custom lengths. If you anticipatethe need to punch sizes other than half letter (8.5"), letter size(11"), A4, A3 or legal size you might look for a machine with fullydisengageable dies. Construction: The construction of this machine is extremely sturdy and the design isaesthetically pleasing. Having the coil inserter near the front of themachine is very handy for inserting purposes (some machines haveinserters on the top). The all metal construction of the machine makesit ideal for medium volume applications.

The only part that couldpotentially break with the ECI is the small clear rubber belt thatdrives the coil inserter. These cost a couple of dollars and are simpleto replace. Recommendation: With a medium duty manual punch and an high quality electric coilinserter I wouldn't hesitate to recommend the CoilMac ECI. If you steptoo far below this machine you will lose the coil inserter, all metalconstruction and durability. Unless I only needed to bind a fewdocuments per week I wouldn't want to give up any of these things.However, if you do a lot of binding, you might want to consider eithera modular system (a separate punch and inserter) or a largercombination system with an electric punch.
