You can get real hardcore and get an Amiga upgraded and on your home LAN, then you can just transfer the ADF from the PC or Internet to the Amiga's RAM disk and then write it to a real disk!
All you really need is a Amiga with a 020 or better with some Fast RAM, OS 2+ (3.x recommended), Hard Drive and a Ethernet card. An Amiga A600 or better yet A1200 would do just fine since you can get a very cheap PCMCIA Ethernet card for it!
