Rectal vs Oral EDTA

hi, i have found edta iv very effective however they are very expensive. Therefore i started to investigate rectal and oral edta. There seems to be alot of arguements over whether rectal or oral is effective in any way. i have read both side pro :http://www.gordonresearch.com and and con : http://drcranton.com/ for the non iv edta
however i cannot find any info on people that have used either form effectively.
Please give me some info on any experiences that you have using either however people that are trying to sell either need not reply

Thanks
Damo
