Using CorelDraw x4 with embroidery plug-ins

I've been reading on the unleashed site and some other "magazines" about plug-ins for Corel that make it possible to create embroidery files from corel files. They all sound great...one or two stand out...but since I'm just learning of the embroidery side of the business I design for (right now I submit to outside source for embroidery digitizing) and I'm primarily familiar with cutting and screenprinting...I'm not sure if there is a reputable plug-in/add-on available that works well with PUNTO. Does anyone have any experience and/or knowledge they'd care to share in this area?

Thanks for sharing your time!
